Clean Cooking Stove Program

 

Introduction

The Matribhumi Improved Cooking Stove for Smoke Free Kitchen is a new initiative taken by HPR Nepal for installation of high efficient cooking stove in households of rural and semi urban villages of Nepal. M-ICS is very innovative, highly efficient and user friendly technology among other Improved Cooking Stove technologies used in Nepal. It was developed and modified by Mr. Madhukar KC.

What is M-ICS ?

In the quest of sustainable form of ICS, M-ICS brought revolution in its kind. M-ICS saves nearly 65% of fire wood and has efficiency as high as 28% making it superior to other improved mud cook stove with efficiency up to only 18%. M-ICS is affordable, easy to use and durable. It does not alter the test of food, cooks food in less time and with less fire wood, significantly reduces cost and saves time spent for fire wood collection.
M-ICS has three innovative components - air supply disk or burner, fiber dye for stove and chimney construction. Due to fiber dye it is very easy to transfer technology to local people for ICS construction. The use of fiber dye and keys simplifies construction and standardizes stoves sizes. By using proper combination of mud, rice husk, cow dung and small bricks or stones, the stove can easily be made with in four hours. Newly developed M-ICS doesn't need air supply disc. Some technological innovation is added in air supply burner which does not demand air supply disc without decrease in overall efficiency of stove.

Features

The main principle of ICS is the complete combustion of fuel. The successful implementation of the ICS in the rural regions is to have simple construction mechanism ensuring the efficient and robust system. There exist many conventional schemes of ICS in Nepal before the introduction of M-ICS. These ICS schemes have not been able to deliver the efficient combustion of fuel and have difficult construction mechanism in the rural regions. In these regards, Mr. Madhukar KC introduced fiber dye, bulging cones in burner and small DC fan to ensure an efficient ICS scheme.
After continuous research and development (13 successive attempts), Madhukar KC was able to fabricate the best possible burner for the cooking stove. A small fan operated by DC 2-3 volts supply and the bulging cones in the burner which hold more oxygen; were able to concentrate heat supply and prevent the excessive loss of useful heat.
The use of fiber dye frame has made the construction of M-ICS more effective, efficient and easy. With the use of proper combination of mud, rice husk, cow dung and small bricks, the stove can be easily constructed within 3-4 hours using these locally available resources. Unlike in other ICS, making of separate mud bricks are not required.
One of the major improvements in this M-ICS scheme is it considerably reduce the indoor air pollution. According to KC, once the temperature in the stove reaches to its maximum limit, the carbon produced from the fuel gets burned down. Due to this, the stove produces very less smoke and yet ensures high temperature for cooking purpose. This mechanism makes it fuel efficient, environment and user friendly as well since it ensures smoke free kitchen. The efficiency of the stove ranges from 24-27% (efficiency of normal ICS is 12-18%) and consumes 60% less firewood.

Implementing Modality  

Awareness Activities: The technology is demonstrated and explained in local schools, VDC, youth clubs and women groups. Inception workshop is organized in the presence of technical persons from HPR Nepal followed by technical training on M-ICS making and installation.

Where HPR Nepal is working in M-ICS?

Currently, HPR Nepal is implementing M-ICS project in Khadgakot, Gulmi Nepal with the objective of replacing 1000 traditional cooking sotve by M-ICS. The Local youth club "Progressive Himali Youth Club" is the implementing partner.
